Title: Diversity combiner control system
IPC: H04B7/08
Filed: 1959-05-20
Abstract: 885,527. Radio receiving systems. COLLINS RADIO CO. May 20, 1959 [Sept. 29, 1958], No. 17184/59. Class 40(5). An angle modulation diversity combiner system includes at least two receivers, each comprising a variable signal response threshold receiver 11, 51, Fig. 1, an amplifier limiter 13, 53, discriminator 25; 75, a weighting signal generator 14, 54, threshold control signal generator 16, 56, means to connect the output of said threshold control signal generator to said variable threshold receiver, a noise cut-off circuit 18, 68 including a phase splitter, a cathode follower, weighting signal disconnect circuit 30, 80, including a D.C. amplifier which responds to the output signal of the threshold control signal generator to provide a D.C. voltage which is applied to the control grid of the cathode follower, the signals being added by a cathode load common to each cathode follower. The adding circuit includes a transistor as a load, the collector being connected to the cathode of the cathode follower, the emitter being connected to earth, fixed base bias being applied. The weighting signal disconnect circuits are actuated respectively in response to particular levels of the input signals. The detected F.M. signal when applied to circuit 18 is split in phase, one phase being applied to the grid and the other phase to the cathode of a cathode follower 28. The output of the two similar circuits is applied to a signal adder 91. In operation different signal levels, due to fading, appear at the discriminator outputs, and the weighting signal from generator 14 will vary according to the signal to noise ratio in known fashion. The bigger the signal the bigger the weighting signal and the cathode follower is driven further above cut off. Where one receiver is receiving only noise the output voltage of the weighting signal generator does not drop sufficiently to provide sharp cut off of valve 28, and a disconnect circuit 30 grounds the output of low pass filter 17 in such conditions to prevent the noise being applied to the adding circuit. Specification 856,892 is referred to.

Title: Recovery of metal values from ocean floor nodules
IPC: C22B1/08
Filed: 1971-05-26
Abstract: 1347715 Metal value extraction DEEPSEA VENTURES Inc 26 May 1971 [26 May 1970] 17242/71 Heading C1A Copper, manganese, cobalt, nickel are extracted from ocean floor nodules by chlorinating or hydrochlorinating the nodules, treating the reaction products to provide the metals in aqueous solution, treating the aqueous solution with a liquid ion exchange reagent to extract copper, nickel and/or cobalt into an organic solution and stripping the desired metal from the liquid ion exchange reagent into an aqueous solution. Nodules, which may be first ground, may then be reacted with hydrogen chloride or chlorine and coal so as to produce chlorides of manganese, copper, cobalt, iron and other metals in minor quantities. These products may at some stage be reacted with air, water or water vapour to convert the iron chloride into iron oxide. In one embodiment water vapour is flowed against the reaction products and the reaction mass is then leached, the insoluble iron oxide being filtered off. In another embodiment, the reaction products are leached with water, and caustic alkali (possibly air also) is then injected into the resulting leach liquor to convert iron chloride to iron oxide. Leaching may also be with sodium sulphate solution. The Specification describes how the hydrochlorinated and chlorinated products may be obtained in fractions. In Example 1 the leach liquor is stripped sequentially of copper, nickel and cobalt by use of solutions (e.g. kerosene) 8- hydroxyquinoline or an α-hydroxy oxime liquid ion exchange reagent. When the cobalt is extracted triisooctylamine solution is used as well. The isolation of manganese chloride from the resulting manganese raffinate solution may be carried out by sulphide precipitation to remove any impurities, evaporation and crystallization. Manganese metal can be isolated from its chloride by use of a fused cell or an aluminium reduction cell.

IPC: D05B69/22
Filed: 1966-04-22
Abstract: 1,140,885. Sewing machines. NAHMASCHINENWERKE ALTENBURG VEB. 22 April, 1966, No. 17700/66. Heading D1G [Also in Division G1] In a sewing machine control system in which the machine is stopped by first coupling it to a slow speed drive and then stopping it when the needle bar is in a predetermined position, the speed and position of the needle bar are determined by a photoelectric pulse generator. The pulse generator comprises photodiodes F 1  F 2  which are alternately shielded from a common light source Li by a screen coupled to the sewing machine shaft to give a series of negative pulses at P the duration of which is indicative of the shaft speed. The pulses charge a capacitor C1 which is discharged between pulses so that the peak value of the output pulses of C1 represents the shaft speed. Normally the bistable circuit F has T4 off and T5 on. When the machine is to be stopped, Sl or S2 is changed over to turn T4 on. T6 conducts to energise an electromagnet Km which operates a clutch to couple the machine to a slow speed drive. The next speed dependent pulse from capacitor C1, provided it is of sufficiently large amplitude (corresponding to a sufficiently low speed of the machine shaft), makes T5 conduct and turns off T4 and T6 to stop the machine by deenergising Km. The position of stopping of the needle bar is controlled by the setting of a bistable circuit A which gives an output at either Al or A2 so that either Fl or F2, which are respectively masked shortly before the upper and lower positions of the needle bar, will be effective in passing pulses to the point P. The setting of circuit A is controlled by switches S1 S2 which can only be actuated alternately.
